Applescript to use Notification Center to give Time Machine updates
Runs as launchagent, but can also be run using Keyboard Maestro and the like. Haven’t tested this too much, but it looks good.
Note: I’m trying to get rid of a couple of menubar items. I don’t have that many (~10 or so, if that many), but if I could remove one or two that would be cool.
For Time Machine progress you/we can use Brett’s GeekTool Time Machine progress indicator. To enter the Time Machine view, you can just open Time Machine.app in /Applications. And if you want notifications for backup progress instead, you can use this nifty thing linked above.
